ff3f3accc6 ntpd: get rid of G.initial_poll_complete
This speeds up syncing - now happens only just
two replies from a peer. Especially useful for "ntpd -q".
Shouldn't have ill effects: if we chose a bad peer,
we will discover it later and switch to another one.

The code is even smaller this way.

936c401077 dhcpd: fix an improper widening conversion
We wanted to detect when tv_sec = unsigned1 - unsigned2
underflows by looking at tv_sec's sign. But if tv_sec
is long and it is wider than unsigned, we get unsigned -> long
conversion which is in this case never negative.

28634924f0 udhcpc: account for script run time
Based on the following user report:

I ran into an issue where I was seeing a long delay in the scripts called
in udhcp_run_script. I was using an old version of OpenWrt (kamikaze)
and a satellite modem. An NTP script was being called and the modem
would sometimes take a long time to respond to the DNS lookup when
it was offline.

This delay started affecting my lease time. The lease that I would
get from my satellite modem before it was online would be short:
only 60 seconds. The delay with NTP and the modem would typically
be about 18 seconds. This would cause the first DHCP renew request
from dhcpc to be a little late. Under certain circumstances,
I could even see the first DHCP renew to occur after the lease
had expired!

fdd957bdc9 zcip: allow our own class B range to be used for ZeroConf
169.254 may already be used by a local network. This patch allows
specifying your own IP range.

Our particular use case is a mesh network, in which the nodes partaking
were using an IP range specifically assigned for the meshing purpose.
As the LAN side of the mesh node could use 169.254, this default range
was not an option.

b434ce7069 ntpd: don't stay at short polling interval
To avoid polling servers frequently slowly increase the interval up
to BIGPOLL when
- no replies are received from a peer
- no source can be selected
- peer claims to be unsynchronized (e.g. we are polling it too
  frequently)

When recv() returns with an error, drop code to try to continue
on network errors: I'm not convinced those cases happen in real life.

a4d564ad7c zcip: fix link-local IP conflict detection
During link-local IP resolution, if a regular ARP request is received
during the ARP probe period, it will incorrectly cause a target IP
conflict.  This then leads to a new IP being picked unnecessarily.

Per RFC 3927, section 2.2.1, we should flag a target IP conflict only if
the source IP is null, the target IP matches our IP, and the source
hw addr does not match our hw addr.

b8ffd11e65 udhcp: add PXELINUX path prefix option (code 210) definition
Like d3092c99, this change adds support for the DHCP "path-prefix"
option, as defined in RFC 5071. We use the string identifer
"pxepathprefix".

Adding this option makes string parsing in the hook scripts simpler.

a6ae999b3b ftpd: escape chroot prior to re-executing ls helper
When we merely chdir to saved "real" root fd,
exec("proc/self/exe") works for static executables but not
for dynamic ones (they can't find their interpreter).

With this patch, we also *chroot* to real root.
As a bonus, this gives us proper usernames, timezone conversion
etc.

e9355c4326 hostname: do not use gethostbyname() for "hostname -s"
There's no reason to call gethostbyname() on the value returned
by uname() when asked just for a short name of a host.  This may
also be wrong, when uname is set to one value, but in /etc/hosts
(or elsewhere) the "canonical" name is different.  This is often
the case for localhost entry in /etc/hosts:

  127.0.0.1     localhost       myname

With this content of /etc/hosts, and uname being set to myname,
busybox hostname -s will return localhost, while regular
hostname utility returns myname.

Fix this by not calling gethostbyname() for the simple
'hostname -s' use.

777be10ebe ntpd: do not invalidate datapoints after step
Used to set p->filter_datapoint[i].d_dispersion = MAXDISP
and clear reachable bits, but this proved to be too agressive:
after step (tested with suspinding laptop for ~30 secs),
this caused all previous data to be considered invalid,
making us needing to collect full ~8 datapoins per peer
after step in order to start trusting them.
In turn, this was making poll interval decrease even after
step was done. (Poll interval decreases already before step
in this scenario, because we see large offsets and end up with
no good peer to select).

2d576e2a22 udhcpc: make DHCP packets to have at least 300 DHCP bytes
Commit b8b72f02 removed all padding from DHCP packets
to fix operation with buggy servers which can't handle
maximum sized packets.  But it introduced a regression
with buggy routers which drop DHCP packets smaller
than 300 bytes (i.e. 342 byte ethernet packets).
Add back some padding to work around.

fbe250db76 httpd: treat errors from stdin correctly.
Fron bug report:

If a CGI or proxied connection is rudely aborted (SIG_{KILL,BUS,SEGV})
then httpd will spin madly the poll loop in:

networking/httpd.c:1080
cgi_io_loop_and_exit()

Upon investigation I found that pfd[0].revents == 0x0018 (POLLHUP|POLLERR),
which leads to empty read, but the pfd[0].fd (STDIN_FILENO) is left open,
and in the FD list given to poll() which immediately returns to once
again inform the loop of (POLLHUP|POLLERR) condition of pfd[0].fd.
This continues until pfd[FROM_CGI].revents != 0

6761d7da83 networking: fix potential overflow in ife_print6()
devname is used by fscanf to store a string specified by '%20s'.

Extract from the man for the '%s' specifier:
Matches a sequence of non-white-space characters; the next pointer must be a
pointer to character array that is long enough to hold the input sequence and
the terminating null byte ('\0'), which is added automatically. The input
string stops at white space or at the maximum field width, whichever occurs
first.

Hence, the right length is 20 + 1 for the '\0'.
